How to pull wires through conduit?
If the conduit is fairly straight you can usually just shove the wires through. Bend a small tight hook on the ends so the end of each wire can get past any rough spots in the pipe. For longer pulls, or if you have more than 2 90 degree bends we usually use a “fish tape” or pull cord. Best way I have found to get a pull cord started is to make a little parachute with a plastic bag and tie that to your pull cord. Then vacuum it through the pipe. If you are pulling big wires you made need to start with a string and use it to pull in a “mule tape” or nylon pull cord and then pull your wires.
How to attach a pull cord to a conduit?
Leave a pull cord twice as long as the conduit, with the extra neatly coiled at one end (and both ends tied). You attach the wire to the middle of the pull cord at the end where you have all the extra, and then when you're done, pull the pull cord back (and coil it up for the next guy). Otherwise, someone invariably doesn't pull a new cord in when they're putting a wire in.
How to snake wire through flex?
If you need to snake wire through a section of flex in between two sections of conduit you can probably take off one end of the flex and get the wires or the snake on through. Remember you are only allowed to have 360 degrees of angles (say, 4 90’s or 4 45 degree bends and 2 90 deg. bends) between pull points, so you may be ahead to put in a junction box or condolet at one end of the flex.

What is conduit wire?
Conduit provides a secure barrier between electrical wiring and exterior conditions that could damage or corrode it over time. A wide variety of conduit is available for both interior and exterior applications, including flexible conduit that allows wires to curve around obstacles. However, rewiring these conduits during repairs and renovations can be challenging. With conduit sometimes running hundreds of feet long, it can be difficult to ensure that wiring runs all the way through without getting caught. Fortunately, there are several methods to pull wire through conduit, and some of the best are covered here.
What to consider when pulling cable?
One of the important things to consider when preparing to pull cable is the type of conduit you’ll be working with.

Pulling wire through conduit with existing wires is difficult because any technique you use may get caught on the existing wires — the conduit mouse and fishing weight method are completely unuseable in these cases for this reason.
What is the mouse method?
The mouse method is a variation of the string method that uses a tool called a conduit mouse or conduit piston instead of a rod.

What to use to pull wires into conduit?
Use a metal or fiberglass fish tape or snake. If the conduit run is long, has several bends, has more than 25% of its area filled with wires, etc., the strength and flexibility offered by a fish tape or snake will make pushing into the conduit much easier. Often times it can be used to pull new wires directly into the pipe - saving time of multiple pulls of increasing strength string / rope. Fiberglass does not conduct electricity and is highly recommended for use instead of metal fish tapes and snakes.
How to pull a light string through a pipe?
